Answer
<span>How does adding a non-volatile solute to a pure solvent affect the vapor pressure of the pure solvent?
</span>Answer The third option The solvent's vapor pressure will not be affected.
<span>To make a 2.0 M solution, how many moles of solute must be dissolved in 0.50 liters of solution?
Answer C. 1.0 mole solute.

The moles of NaOH used in the titration would be 0.00177 moles while the molarity of the vinegar will be 0.885 M
<h3>Titration calculation</h3>
Recall that: mole = molarity x volume
In this case, the molarity of the NaOH= 0.1 M
Volume of NaOH = 17.7 - 0.0 = 17.7 mL
Mole of NaOH used = 0.1 x 17.7/1000 = 0.00177 moles.
Since NaOH and vinegar have 1:1 mole ratio, the mole of vinegar will also be 0.00177 moles.
Molarity of vinegar = mole/volume = 0.00177/0.002 = 0.885 M
